The Canadian promo for Tuesday's 'Pretty Little Liars' episode 'Cover for Me' (4x22) is here and it has us seriously wondering if Spencer took that shovel and dug Ali's grave the night she disappeared.

In the above promo, Spencer awakens to find her bed covered in dirt and locates a note which reads, "I know you dug her grave. Now I'm digging yours. Kisses, -A"

To make matters worse, she seems to think that her parents knew about the event all along and chose to hide it from their daughter to protect her. This certainly goes in line with our glimpses of her returned memories in which Spencer dangerously brandishes (read: swings around) a shovel.

Tune in to ABC Family tomorrow (March 4) at 8PM ET to see just what Spencer's memories reveal.
